Key parameters
Measuring range
Remote analyzer for Rosemount 6888A/6888C O2 probes; user-configurable O2 0–50% via connected probe; factory cal 0–10%
Accuracy
Stochiometer reducing-condition indicator ±0.1% of reading or 0.1% O2 (whichever greater); probe repeatability ±0.75% of reading or 0.05% O2
Output
4–20 mA HART® 5; FOUNDATION™ Fieldbus option; up to two digital HART channels or one traditional-architecture input
Supply
120/240 Vac 50/60 Hz; digital single/dual 12 VA max; flame-safety interlock version up to 260/1020 VA (probe heater driven)
Ambient temperature
−20 to +50 °C (+4 to +122 °F) for 6888 Xi
Display
Large backlit local operator interface LCD with keypad
Fits remote zirconia O2 probe control where you need Rosemount 6888 Xi electronics with HART/4–20 mA, local interface, and advanced combustion diagnostics.
Key advantages
- Remote analyzer — Rosemount 6888 Xi remote analyzer for general-purpose locations
- Probe interface — 1OXY/2OXY/3OXY digital HART inputs or 4OXY traditional architecture (120 V heater probes)
- Communications — HART / 4–20 mA to PLC or DCS; local operator interface
- Diagnostics — Plugged-diffuser diagnostic; stochiometer for reducing conditions; programmable reference; extended temperature function
- Mounting / cable — Panel or 2 in pipe/wall kits; traditional-architecture cables 20–150 ft class
Typical applications
- Remote electronics for Rosemount 6888 in-situ O2 probes.
- Dual-channel HART probe supervision from one Xi.
- Combustion sites needing stochiometer / plugged-diffuser diagnostics.
Selection guide
- Measurement code — 1OXY / 2OXY (heater interlock) / 3OXY dual / 4OXY traditional
- Feature enables — stochiometer, programmable reference, extended temperature, plugged diffuser (single/dual)
- Mounting kit — none / panel / pipe-wall
- Cable — only for traditional architecture probes
Common mistakes
- Ordering 4OXY cable lengths for digital HART probe architectures.
- Assuming 44 V World Class heaters are supported — published 6888 Xi measurement codes are for 120 V heater probes.
- Ignoring Emerson obsolete/replacement status on new projects — confirm current offer on RFQ.
When to RFQ / what to tell us
- Probe type (6888 digital vs traditional) and channel count.
- Feature enables (stochiometer, diffuser diagnostic, etc.).
- Mounting/cable; quantity; ship-to; confirm current vs replacement product.
